Quantum oscillations of self-dual Abrikosov-Nielsen-Olesen vortices

The mass shift induced by one-loop quantum fluctuations on self-dual Abrikosov-Nielsen-Olesen (ANO) vortices is computed using heat kernel/generalized zeta function regularization methods. The quantum masses of superimposed multivortices with vorticity lower than five are given. The case of two separate vortices with a quantum of magnetic flux is also discussed.
